One of four people arrested after a chase that involved the shooting of a Denver police sergeant last week has been released from the Downtown Denver Detention Center and won’t face charges in the case, the Denver District Attorney’s Office said Thursday.

Alyssa Moralez, 21, had been held on four counts of attempted murder of a peace officer and a count of assault after the Jan. 16 incident, in which police said she was a passenger in a red Dodge pickup that led police on a chase through a northwest Denver neighborhood.

At least one of the occupants opened fire on officers, hitting Sgt. Robert Motyka station in the shoulder. Police said the shooting — in which officers shot and killed one of the suspects, John Montoya — capped a day of violence around the metro area by those inside the truck. The vehicle was spotted during shots-fired incidents in Aurora and Denver’s Montbello neighborhood earlier in the day, police have said, a “mini crime-spree” that precipitated when John Montoya, enraged over the death of his infant daughter, held a relative at gunpoint in Thornton.

The district attorney’s office would not say why prosecutors are not charging Moralez. On Thursday, they formally charged three other people with four counts each of attempted first-degree murder and five counts each of attempted assault. They are Jude Montoya, 21, Chuck Montoya, 34, and Michael Valdez, 38.

The truck crashed into a tree at West 39th Avenue and Osage Street. An officer told investigators its driver tried to run him over during the pursuit, at which point he fired shots. Denver police said six officers were placed on paid leave after the incident, as is protocol in officer-involved shootings.

Motyka, who leads one of District 1’s Street Crime Attack Teams, is recovering at home.
